[Everywoman]

So, sometimes when I need to tell my parents something I know they're not going to accept, I put it off as long as I can. I'm in that situation now and still don't know how to bring it up.

Let me start at the beginning. I'm 25 years old and still live with my parents (in California). My parents are the type of people who think I should live at home until I'm married and that pre-marital sex is the worst thing anyone can ever do. I haven't told them I'm not a virgin and I'm sure they know I'm not, but they act like I am. In September, I went to Australia and met a really fantastic guy who I met through a friend. Ever since then, we talk on the phone for hours and hours. I'm in between jobs now and decided to take two weeks off before I start my new job and me and this guy decided it would be a nice time for me to go back over there and get to know him a little bit better. All expenses paid and I would be staying with him and his sister. Now, my mother already has issues with the fact that I talk to him so much and that he's on the other side of the world. I leave for Aus on Thursday and am going to be there for one week, but I don't know how to bring it up and don't know how I am going to deal with the guilt trips of not spending time with the family on my time off and how I'm being immoral and not respecting myself if I do go on this trip.

I really need some good concrete advice because I don't feel like I'm doing anything wrong, but my parents will see it that way. How should I approach this?
